slice#
- UnstructuredGridFilters.slice(normal='x', origin=None, generate_triangles=False, contour=False, progress_bar=False)#
Slice a dataset by a plane at the specified origin and normal vector orientation.
If no origin is specified, the center of the input dataset will be used.
- Parameters
- normal
tuple
(float
)or
str
Length 3 tuple for the normal vector direction. Can also be specified as a string conventional direction such as
'x'
for(1, 0, 0)
or'-x'
for(-1, 0, 0)
, etc.- origin
tuple
(float
) The center
(x, y, z)
coordinate of the plane on which the slice occurs.- generate_trianglesbool,
optional
If this is enabled (
False
by default), the output will be triangles. Otherwise the output will be the intersection polygons.- contourbool,
optional
If
True
, apply acontour
filter after slicing.- progress_barbool,
optional
Display a progress bar to indicate progress.
- normal
- Returns
pyvista.PolyData
Sliced dataset.
Examples
Slice the surface of a sphere.
>>> import pyvista >>> sphere = pyvista.Sphere() >>> slice_x = sphere.slice(normal='x') >>> slice_y = sphere.slice(normal='y') >>> slice_z = sphere.slice(normal='z') >>> slices = slice_x + slice_y + slice_z >>> slices.plot(line_width=5)
